Moreover, we only consider an EORC based on bandpass feedback system modelled via (REF ); this is a realistic scenario as practical loss in the experimental system [1]}, [2]}, [3]} demands the use of an RF amplifier. The bandpass filter parameters used throughout are \(f_L=10\)  kHz and \(f_H=10\)  GHz; such a broadband filter is achievable in practice noting the availability of ultrawide bandwidth photodetectors, e.g., [4]} and RF amplifiers, e.g., [5]}. The delay time of the EORC used is the same as in the previous Sections \(\tau =1\)  \(\mu \) s. The impact of different numbers of virtual nodes (or number of mask points) \(N_x\)  is now investigated.
